Nvidia's Q1 FY27 results materially improve demand visibility across the optics, networking and photonics stack. Revenue hit $81.6B, up 85%, with networking at $14.8B, up 199%, and Nvidia named multi-year optics deals with Coherent, Corning and Lumentum plus a Marvell partnership on NVLink Fusion and silicon photonics. AI cloud, industrial and enterprise revenue grew 31% sequentially versus 12% for hyperscale, so the buildout is spreading. Vera Rubin ramps in Q3. x.com
Optical networking value spans a six-layer supply chain priced unevenly, beyond the transceiver and CPO vendors behind Goldman Sachs' $154 billion market call. Soitec's photonics-SOI wafers dominate the substrate layer yet are priced like a cyclical supplier. STMicro's AWS co-developed PIC chips target over $500 million of 2026 datacenter revenue. Coherent supplies indium phosphide lasers, Marvell optical silicon, Sivers laser parts, and Smartoptics' Q1 cost was a structural expansion. x.com
Repeat orders and larger new-customer orders are driving SmartOptics' growth. Q3 revenue rose 80% and EBIT 340%, with strong cash flow. Ciena and Nokia are busy serving hyperscalers; SmartOptics should scoop up all other smaller customers. Its 300M revenue target by 2030 suggests more growth. x.com
AI data-center spending flows beyond GPUs and operators into networking, optics, power and cooling. Nvidia, AMD, Broadcom and Marvell supply chips; Arista, Nokia and Credo connectivity; Applied Optoelectronics and Lumentum optics; Vistra, Constellation and Bloom power; Vertiv and Modine cooling. Meta's $140B spending this year illustrates the scale, per a commenter with whom the point is agreed. x.com x.com
Marvell risks paying a peak-scarcity price for Lumentum if optical supply catches up by 2028-30. The proposed ~$99B deal values Lumentum at roughly 20x guided annualized revenue and 58x estimated after-tax operating income, while Lumentum, Coherent and Chinese suppliers are adding laser capacity. The DSP-and-laser combination has strategic logic, but durable scarcity economics and Nvidia's response remain uncertain. x.com
Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com x.com
Networking is the next AI hardware trade after memory, whose share of rack value rose from 15% to 35%. Optics is moving inside the server, as Nvidia's Feynman architecture builds in co-packaged optics and silicon photonics. Scale-across networking could grow 30% a year just linking existing data centers, as inference moves closer to users and training spreads across sites. Supply is tight: Lumentum's CEO said it can meet only 30% of expected 2027 demand and sees optics tighter than memory. x.com
Applied Optoelectronics, Lumentum and Coherent face share losses at US hyperscalers to Innolight. Channel checks favor Innolight gaining share in Q2 2026, at the expense of those three. Per @poezhao0605, a $7B Hong Kong IPO, the largest in years and upsized from $5B on strong demand, has cleared its listing hearing. x.com
Corning's optics business looks ready for a comeback as its fiber and high-density optical connectivity move data across massive AI GPU clusters. Optical sales rose 32% year over year to $2.07 billion, EPS is expected to more than triple by 2028, and the business is backed by major AI infrastructure deals with NVIDIA, Meta and Amazon. x.com
Coherent's pivot to AI optics is paying off as copper gives way to optical links inside large AI clusters. Quarterly revenue topped $2 billion for the first time, up 42%, with datacenter and communications up 59% to 79% of sales. Multi-year contracts with AI leaders including Nvidia extend order visibility into 2028. It launched its PhotonLink interconnect platform at ECOC 2026, and its indium phosphide, VCSEL and 6-inch wafer strengths give it a moat in 800G and 1.6T transceivers. x.com
Scale-up moving to optics adds demand for optical suppliers even if new AI architectures need fewer switches. Bigger data centers and more GPUs add to that need; Jensen Huang expects future optics requirements to be several orders of magnitude above what NVIDIA ships today. This challenges the optics bear case for Lumentum, Coherent, Tower Semiconductor and Credo. x.com
Coherent now has credible exposure to almost every optical architecture hyperscalers are exploring, and its Nvidia deal materially de-risks that roadmap. Nvidia's nonexclusive pact adds a multibillion-dollar purchase commitment, a $2B equity investment and access to five CPO product families. First CPO/NPO revenue targeted for H2 2026 matches Nvidia's timing. Data center and communications are already 72% of revenue. Qualification, standards, concentration and margins remain unsettled. x.com
